I noticed that many kids are wearing glasses from young. Either they are looking into iPad all the time or they have vitamin A deficiency . Adding carrots into the children's meal is good for them. Children should not be allowed to face the computers or iPad for a long period of time. It will damage their eyesight and will cause them to wear glasses from young. When my Piggies were toddlers, I always add carrots and spinach to their porridge. Thus , they have better eye sight than my two other nephews. They started wearing glasses since they were four years old. I guess my sis-in-law did not give them enough vitamin A . Lucky for them , we have an optical shop near our place that provides glasses for child and adults. They have a great selection of affordable glasses to fit kids. Somehow it is important to add vegetables / fruits with vitamin A to your kid's meal .
